#3 retain file list position during browsin

[Ricardo Contreras]

/* idea for possible implementation... this is a *would
be nice* luxury idea... but not really necessary. */

retain the position (gtk_clist_get_vadjustment ()) of
the directory_list during file system browsing by
keeping a GHashTable of the directory entries.

This would allow you to browse directories more
consistently. If you have a directory with lots of
entries (as I do, my main music library contains > 150
entries for artists) then whenever you hit "../" to go
back to the main directory, it would be nice to have
the display be where you were previously... and not
have to start from the top of the dir.
